The method for calculating Pearson correlation coefficient is given, details are not described herein.
It optionally, can be according to formulaIt is corresponding to calculate each target component
Weight.In above-mentioned formula,For indicating i-th of target component PiCorresponding weight,For indicating fine and close oil well
Production Q and target component PiRelevant Pearson correlation coefficient, n are used to indicate the quantity of target component.
Illustratively, the corresponding Pearson correlation coefficient of target component that following table one provides introduces the calculating side of weight
Method:
Table one
| Serial number | Target component | Pearson correlation coefficient | Weight (%) |
| 1 | Reservoir porosity (%) | 0.648 | 31.92 |
| 2 | Reservoir thickness (%) | 0.312 | 15.37 |
| 3 | Reservoir brittleness index (%) | 0.519 | 25.57 |
| 4 | Hydrocarbon source rock total content of organic carbon (%) | 0.387 | 19.06 |
| 5 | Hydrocarbon source rock thickness (m) | 0.164 | 8.08 |
Above-mentioned two mesh is introduced by taking reservoir porosity and hydrocarbon source rock total content of organic carbon as an example referring to the data in table one
Mark the calculation method of the corresponding weight of parameter.
The weight of reservoir porosity are as follows:
The weight of hydrocarbon source rock total content of organic carbon are as follows:
According to above-mentioned calculating, the weight of each target component can be determined, thus under selection when a bite densification oil well position,
Emphasis considers the big target component of weight, and the influence due to the big target component of weight for fine and close oil well output is bigger, also
Can reference target parameter determine the big fine and close oil well position of yield.
Step 103, in the target area, determines at least two target locations, and obtains the target ginseng of each target location
Number.
Target location is the point of the different location in target area.In the target area, the stratum characteristic of different location is not
Together, it also meaning that, the target component obtained from different location is different, and from the oily well yield of densification disposed and institute
From the point of view of the target component in place, influence of the different target parameter for fine and close oily well yield is different.In the embodiment of the present invention
In, then it is according to fixed target component for the fine and close oily influence of well yield and the target component of target location, in advance

Mark parameter reflection is suitble to dispose fine and close oil well in the target location, and some target component reflections are not suitable for disposing in the target location
Fine and close oil well, in this case, it is necessary to which in conjunction with different target parameter, when determining fine and close oil well position, shared weight, synthesis are examined
The target location is considered if appropriate for the fine and close oil well of deployment.Also, since target area is usually located at dessert area, dessert area area compared with
Greatly, it is usually deployed more fine and close oil well, correspondingly, a large amount of places would generally be selected as target location, from a large amount of target locations
The deployment place of the multiple fine and close oil wells of middle determination.If directly according to the target component of each target location and the weight calculation mesh
The point value of evaluation for marking place, then can generate a large amount of calculation amount, bring great load to computer equipment.It is calculated to reduce
Amount according to the size of target component, has divided multiple grades, each grade in embodiments of the present invention for each target component
Corresponding identical grading evaluation coefficient, and according to the comprehensive scores of grading evaluation coefficient and weight calculation target location, in this way, only
It need to calculate primary, so that it may obtain the score value of grading evaluation coefficient all target locations all the same, greatly reduce computer

| Reservoir thickness (%) | ≥10 | 5-10 | 2-5 | < 2 |
| Reservoir brittleness index (%) | ≥60 | 40-60 | 30-40 | < 30 |
| Hydrocarbon source rock total content of organic carbon (%) | ≥3.5 | 2.0-3.5 | 1.45-2.0 | < 1.45 |
| Hydrocarbon source rock thickness (m) | ≥8 | 5-8 | 2-5 | < 2 |

Successively select required amount of target location as the deployed position of fine and close oil well.It should be noted that threshold value can be by petroleum
Scout combines the factors such as development zone geological condition and the demand to fine and close oil yield to be configured, for the specific of threshold value
Size, it is not limited here.
Also, according to the oily well yield of the densification disposed and target component, different target place can also be estimated
The yield of fine and close oil can illustratively select fine and close according to the volume range of point value of evaluation and the fine and close oil well estimated
Oil well position:
